"Solution Processable Two Dimensional Materials for Electronics & Energy Applications"Chemical exfoliation of layered two-dimensional materials such as graphite and transition metal chalcogenides allow access to large quantities of atomically thin nanosheets
that have properties that are distinctly different from their bulk counterparts.
Although 2D materials have recently
become popular, their fabrication via exfoliation of bulk crystals has been known for decades. For example,
Brodie first exfoliated graphite into atomically thin oxidized form of graphene in 1859. In the case of layered transition
metal dichalcogenides (LTMDs) such as MoS2, WS2, MoSe2, WSe2, etc., Frindt et al. performed seminal work in
the ‘70s and ‘80s. We have revived these techniques to obtain a wide variety of chemically exfoliated twodimensional
nanosheets and utilized these materials in
electronics and energy applications. In this presentation, I will highlight some of our key contributions with graphene
oxide (GO) and LTMD nanosheets.
